    Video Accelleration OK, but Firefox performance quite poor!

    After following this excellent support thread http://ubuntuforums.org/showthread.php?t=1980663 I got my ATi card working ok, but now I'm facing great performance issues in Firefox (12.0) in plain html pages (like this one), nothing about flash or animations or videos.

    When scrolling the page up and down the scrolling gets pretty slow! Also this issue appears when browsing HTML5 pages like games, it get's really slow!

    Thanks in advise!

    Try starting Firefox in safe mode to rule out problems with add ons.

    Code:
    firefox -safe-mode

    Nope, ran
    Code:
    firefox -safe-mode
    But no luck

    On pages like this http://9to5mac.com/, scroll sucks. Very poor performance!

    It says that failed to open VDPAU backend libvdpau_nvidia.so, and can not find that file.

    VDPAU is an NVIDIA technology.

    Do you have an NVIDIA driver installed?

    We just got your ATI card going yesterday!

    Well....

    I'll have to think on that a bit.

    Code:
    Failed to open VDPAU backend libvdpau_nvidia.so: cannot open shared object file: No such file or directory
    Hardware acceleration for Flash videos is enabled by default, but it is only supported by NVIDIA cards. So this error message will appear, if the library for NVIDIA's VDPAU backend is installed on your AMD/ATI based system. So either delete the library or ignore the messages.

    I'm not sure what might cause the slow performance (even on sites without flash content). Try to monitor the running processes while browsing some websites.
